【摘要】 层次移动IPv6协议中,链路转交地址和区域转交地址的重复地址检测操作需要的时间占IP层切换延时的绝大部分。提出了一种层次移动IPv6改进协议,引入链路转交地址池和区域转交地址池,从地址池直接获取转交地址,避免了重复地址检测操作。实验表明,相比层次移动IPv6协议,有效缩短了切换延时。更多还原

【Abstract】 In Hierarchical Mobile IPv6(HMIPv6) protocol,the Duplicate Address Detection(DAD) operations for the On-link Care-of Address(LCoA) and Regional Care-of Address(RCoA) greatly impair the mobile node’s inner-MAP and inter-MAP handover performance.The HMIPv6 protocol based on care-of address pool which introduced LCoA pool and RCoA pool into HMIPv6 was proposed,care-of addresses were got from the pools directly,and therefore the DAD operations for the LCoA and RCoA were avoided.The experiment results show that the proposed protocol greatly reduces the handover latency.更多还原
